The mother gunned down yesterday after ramming a White House barrier because she thought President Obama was stalking her was prescribed schizophrenia medication after telling police she was the 'Prophet of Stamford', it emerged today.

Miriam Carey, 34, was taken for a mental health evaluation after an encounter with Connecticut police almost a year ago, in which she claimed to be a prophet and said the President was going to place the city of Stamford under lockdown, according to CBS.

She also believed he had beenelectronically monitoring her Connecticut home in order to broadcast her life on television like in the movie The Truman Show.

Authorities did not alert the Secret Service about the mother-of-one as they had no evidence she had ever made any kind of threat against Obama.

ABC News reports that cops had twice in 2012 been called by Miriam Carey's boyfriend, who reported the woman was delusional, acting irrationally and putting her infant daughter in danger.

Rescued: This is the one-year-old daughter of Miriam Carey who was miraculously rescued safely from her mother's bullet-riddled car

Last night her mother revealed the 34-year-old has suffered from postpartum depression since giving birth to her daughter Erica last year.

These revelations are the first clues as to what led a seemingly happy dental hygienist to snap and drive her Infiniti luxury sedan 270 miles from her home in suburban Stamford to Washington, DC - where her rampage put the nation's capital on lock-down Thursday.

Carey's 18-month-old daughter Erica - who was in the back seat - was not injured, despite the Secret Service and U.S. Capitol police firing up to 15 shots into her car.

Little Erica was rescued from the bullet-riddled car after her mother was shot dead. She is currently in the custody of child services workers.

It also emerged today that Carey's friends said she was upbeat and 'normal' until she fell down some stairs and hit her head in April 2012.

When Carey was receiving treatment for the injury in the hospital, she learned that she was pregnant.

She received a handicapped parking permit because of the injury, but doctors from the medical suite where she worked complained that she was tying up parking in front of the building, according to CBS.

The resulting dispute from this ended with her losing her job.

It emerged today that Carey had beensued by her condominium association for failure to pay fees.

The complaint filed in November by the association for the Stamford building said Miriam Carey had failed to pay her fees in full since August 2010 and owed the association $1,759 in addition to collection costs.

The lawsuit was settled in February.

The lawsuit by the Woodside Green Association indicates Carey took out a mortgage on her Stamford condo in the amount of $237,616 in September 2009.

Idella Carey told ABC News that her daughter Miriam 'had postpartum depression after having the baby' in August 2012.

'A few months later, she got sick. She was depressed.... She was hospitalized,' Mrs Carey added.

She thought Carey was taking Erica to a doctor's appointment in Connecticut.

The 34-year-old has five sisters, one of whom is an NYPD officer.

Another, Amy Carey - who is a nurse in Brooklyn - expressed disbelief when told about what happened to her sister by a Washington Post reporter.

'That's impossible. She works, she holds a job. She wouldn't be in D.C. She was just in Connecticut two days ago,' she said. 'I spoke to her...I don't know what's happening. I can't answer anymore.'

Dentist Barry Weiss told NBC Connecticut that Carey was working for him in January 2012 when she suffered a fall and missed two-to-three weeks of work.

When she returned she was pregnant but he later fired her in August 2012 after patients complained that she was too rough.

She was not married to the father but 'seemed happy' about the pregnancy, the former boss said.

Authorities said the single-mother had a 'history of mental illness' but did not elaborate.

Neighbor Erin Jackson told ABC she believed Carey lived in the Stamford home with the baby and the girl's father.

Asked if she believed Carey suffered from a mental illness, Jackson said 'absolutely' and revealed she had her tires slashed in an incident last year in Connecticut.

Police, including FBI and bomb disposal units, surrounded a home in Stamford on Thursday evening that authorities say is linked to the investigation, but won't give specifics.

Police there said they were awaiting a search warrant from Washington, though 50 people from the apartment building already were being evacuated for the night.

BRAVE CAPITOL POLICE RISKED THEIR LIVES FOR FREE BECAUSE OF GOVERNMENT SHUTDOWN

When Congress reconvened after the lock-down Thursday afternoon, the Capitol Police officers who stopped Miriam Carey got a standing ovation - but not much else.

The 1,800 officers who protect the nation's capital are currently working for free thanks to the government shutdown.

The officers are considered essential staff - so they are turning up for work, but won't get paid for their service until the impasse ends and Congress agrees to fund the government.

Congressmen tweeted about hiding in coat rooms and ducking behind cars during the harrowing moments before Carey was killed within sight of the Capitol Building.

Meanwhile, the officers who risked their lives haven't been paid since Tuesday, thanks to Congress' in-fighting over whether to pass a Continuing Resolution to fund day-to-day operations.

Carey's former boss of eight years, Dr Steven Oken, said in the eight years he knew Miriam she was 'always happy' - and not interested in politics. Neighbors told the New York Daily News she was 'a nice young lady, stable'.

'I would never in a million years believe that she would do something like this,' he told ABC. 'It's the furthest thing from anything I would think she would do, especially with her child in the car. I am floored that it would be her.'

That portrait contrasts starkly with the woman who sent Congressmen diving for coatrooms in the Capitol Building and tourists fleeing in terror after she tried to force her way into an entrance to the White House about 2pm on Tuesday.

Despite the sensitive location, Capitol Police Chief Kim Dine said: 'This appears to be an isolated incident.There is no nexus to terrorism.'

Witnesses say Carey plowed through a temporary barrier and hit a Secret Service agent who was trying to wave her off - sending him flying onto the hood of her car.

The Secret Service opened fire on her car as she turned and fled.

Police pursued her through the streets of Capitol Hill during a frantic chase that hit speeds up to 80pmh.

Video footage shows the Capitol Police officers - who have not been paid since Tuesday because of the government shutdown - surrounded Casey's car - guns drawn. At one point an officer even sticks his weapon inside her open passenger-side window.

Carey is reportedly a 32-year-old dental hygienist who lived in Stamford, Connecticut

But even being blocked in by cops didn't stop her, she wheels the car around, hitting a police cruiser and nearly striking several officers, and flees.

Officers can be heard shooting at her car as it drives off.

Moments later, Carey was shot and killed - within sight of the Capitol Building, and just behind the U.S. Supreme Court.

She was not armed.

The Secret Service agent she hit sustained minor injuries.

A veteran Capitol Police officer who was rushing to the scene smashed into an emergency barrier in his squad car and had to be airlifted to the hospital. His injuries were not major, Chief Dine said.

Carey grew up in Brooklyn, New York. A neighbor of her sister, Amy Carey, told MailOnline the two sisters don't get along.

'They just don't see eye-to-eye,' Ruth Macon said.

A website for the dental practice said that Carey brought 'a delightful bedside manner,' as well as a degree is nutrition to help patients.

Both Secret Service agents and Capitol police officers opened fire on the car in at least two locations near the White House and Capitol Hill.

President Obama, who was taking part in an engagement in Maryland, was briefed on the incident.

Matthew Coursen was on his way to a legislative office building when the car sped by him.

He said: 'The car was trying to get away. But it was going over the median and over the curb.

'The car got boxed in and that's when I saw an officer of some kind draw his weapon and fire shots into the car.'

'Now the cop has his weapon out. The car kept trying to get away. Then he fired shots.'

Eye-witness Frank Schwing, who lives in DC, told reporters that when the vehicle approached the area of the Capitol building, several squad cars stopped it and officers 'came out with their guns drawn'.

The armed officers tried to open the passenger side door, he said.

Mr Schwing continued: 'At that point, the driver slammed into reverse, slammed into a cruiser, did a 180 (degree turn), took off, and at that point, there were a half dozen or so shots fired.'

During the lock down, Rep. Jared Polis (D-Colo) told MSNBC: 'We’ve locked the doors. We closed the window shades. And we are awaiting further instructions.

'We’re more or less cut off here. We’re watching TV and just trying to figure out what happened.'
